摘要:
A power tool having a plastics material housing and a power output spindle is provided with a tube-like metal member in the front end of the housing. A bearing is received within the tube-like member for supporting the spindle. The tube-like member has at the front end thereof radially outwardly extending tabs for dissipating heat therefrom. The tabs are preferably partially embedded in the plastics material of the front end of the housing for anchoring the member therein, alternate tabs preferably being angled rearwardly. The member may also support ratchet teeth of a hammer drill. A fan may be mounted on the spindle in the region of the front end of the member for facilitating dissipation of heat from the radial tabs.

摘要:
A device for simultaneously and/or group-wise random measuring fluorescent light emitted by sample-reagent mixtures contained in a plurality of reaction vessels.In order to measure fluorescence light for each reaction vessel with high sensitivity and accuracy and at the lowest possible cost the device according to the invention has an array of photodiodes built on a chip. Each of the photodiodes of the array is configured to receive fluorescent light emitted by a sample-reagent mixture contained in one of said plurality of reaction vessels and to provide an output signal representative of the intensity of said fluorescent light. An integrated electronic circuit is connected to the said array of photodiodes for processing output signals provided by photodiodes of the array. The integrated electronic circuit is mounted on the chip on which the array of photodiodes is built.The output of each of the photodiodes of the array of photodiodes is directly connected to a corresponding input of the integrated electronic circuit.
